Dinetus (Venustidinetus) tunisiensis Khedher & Mokrousov, 2020

Dinetus tunisiensis Khedher & Mokrousov in Mokrousov & Khedher, 2020: 119 , ♀, ♂. Holotype: ♀, Tunisia: Djerba Island, 2 km N Agir , 33.773°N, 11.037°E (ZIN).

Description female (after Mokrousov & Khedher 2020).

Colour. Head, body and legs black, pale yellow are spots on pronotum, scutellum, metanotum, apical ring on propodeum and big lateral spots on tergum II. Ferrugineous are mandibles basally, underside of scape, fore tibia (except underside) and fore tarsus. Antenna black, underside of scape and antennomere 2 ferrugineous.

Morphology. Apical margin of clypeus with short lamella. Mandible with distinct tooth basally and weak notch distally. Vertex with scattered fine puncture. Mesosoma with obsolete chagrined sculpture. Propodeal enclosure with chagrined sculpture laterally, central area with oblique striae basally and transverse striae apically. Head, mesosoma and metasoma without erect setae. Anterior part of mesopleuron, lateral part of propodeum and hind coxa with appressed silver pubescence. Head and body without erect setae. Fore femur flattened ventrally and with keel posteriorly. Outer vein of subdiscoidal cell (cu) oblique, distinctly converging with the nervulus (cu-a) (see fig. 2). Body length 4.9–5.5 mm.

Description male.

Colour. Similar to female with more extensive yellow: mandibles basally, clypeus, face below antennal sockets, gena partly.

Morphology. Frons chagrined, anterior of ocelli and on vertex with distinct punctures. Antennomeres 9–12 with weak indentation ventrally. Fore trochanter and femur without teeth. Otherwise similar to female. Body length 4.0– 4.5 mm.

Distribution. Tunisia (type locality). The record from Morocco ( Olszewski et al. 2020) is questionable (Mokrousov, personal communication). The male pictured by Olszewski et al. (2020) differs markedly in the shape of antenna and colour of legs from the description of D. tunisiensis .
